GM Part Warranty
The standard warranty for most OEM replacement parts (be they GM brand or AC Delco brand) is at least 12 months with unlimited mileage, but there are parts with more coverage. GM replacement engines and transmissions, for example, can have 18 or 36 months of coverage with 100,000 miles. GM Performance Engines can be covered for 24 months or 50,000 miles.
While the standard GM and AC Delco parts warranty is good, we don’t think 12 months of coverage is sufficient for most parts. This is why GMPartsOnline.net is one of the only online GM part retailers to offer extended coverage. For a small fee, anyone who buys GM parts from us can double the factory warranty coverage. It’s a great value we’re proud to offer.
To purchase extended coverage, simply find and add parts as you normally would. You’ll see that the coverage is automatically added to each part.
